PWM Interrupt Flag — Any change from passive to asserted (active) state or from active to passive state will be
flagged by setting the PWMIF flag = 1. The flag is cleared by writing a logic 1 to it. Writing a 0 has no effect.
0 No change on PWM5IN input.
1 Change on PWM5IN input
PWM Interrupt Enable — If interrupt is enabled an interrupt to the CPU is asserted.
0 PWM interrupt is disabled.
1 PWM interrupt is enabled.
PWM Restart — The PWM can only be restarted if the PWM channel input 5 is deasserted. After writing a logic 1
to the PWMRSTRT bit (trigger event) the PWM channels start running after the corresponding counter passes
next “counter = 0” phase.
Also, if the PWM5ENA bit is reset to 0, the PWM do not start before the counter passes 0x0000.
The bit is always read as 0.
PWM Shutdown Output Level — If active level as defined by the PWM5IN input, gets asserted all enabled PWM
channels are immediately driven to the level defined by PWMLVL.
0 PWM outputs are forced to 0
1 PWM outputs are forced to 1.
PWM Channel 5 Input Status — This reflects the current status of the PWM5 pin.
PWM Shutdown Active Input Level for Channel 5 — If the emergency shutdown feature is enabled
(PWM5ENA = 1), this bit determines the active level of the PWM5 channel.
0 Active level is low
1 Active level is high
PWM Emergency Shutdown Enable — If this bit is logic 1 the pin associated with channel 5 is forced to input
and the emergency shutdown feature is enabled. All the other bits in this register are meaningful only if
PWM5ENA = 1.
0 PWM emergency feature disabled.
1 PWM emergency feature is enabled.
